During practical application, in cable to be fixed on by the connection of bolt by left-hand cylinder body and right cylindrical shell, and the screw thread in groove in left-hand cylinder body and right cylindrical shell arranges and can prevent cable from slipping away further, plays the better anti-effect that slips away.
Cable position-limited hoop is also provided with, the cylindrical channel that cable position-limited hoop forms across left-hand cylinder body and right cylindrical shell between 2 described bolt a.
The two ends of described cable position-limited hoop are vertically hold, and middle part is for having flexible arch section.The setting of cable position-limited hoop plays dual non-slip from effect, and the flexible arch section of cable position-limited hoop along with the external diameter size adjustment fixed range of cable, can carry out tether cable and prevent from slipping away more flexibly.
Described sealing ring is provided with multiple columniform groove.
The radius of multiple described groove is unequal.This set of sealing ring can be applicable to the cable of the different-diameter simultaneously introduced, and meets the actual demand introducing different cable.
The trumpet-shaped radian of described platen afterbody is 75-85 °.The setting of radian is time conveniently flexible cable enters, and can not be introduced into mouth and lose, be conducive to entering smoothly of flexible cable.
Described sealing ring is for adding ageing-resistant rubber.Sealing ring is generally made up of rubber, in permanent use procedure, because the generation of the aging phenomenon of rubber, the elasticity of sealing ring can fade away and lose sealing function, and then affect the anti-explosion safety performance of electrical apparatus for explosive atmospheres, add the ageing properties that appropriate age resister can improve sealing ring to sealing ring, thus improve the usability performance of sealing ring.
To sum up, the beneficial effects of the utility model are:
The utility model has been set up anti-cable and have been slipped away device on the basis of original device, and this device, by the cable clamping that will be arranged in device by bolt tightening, prevents cable slippage, thus can meet the normal demand used.
